See Figure 4-8 for the following procedure.
For quick identification by repair workers, clearly mark
damaged areas with brightly colored tape.
1. Sandblast to remove corrosion. Do not grind!
2. Determine reduction in cross-sectional area.
3. If reduction is less than 3% of strap cross-sectional area,
paint strap to maintain continuous protective coating.
4. If reduction is 3% or more of strap cross-sectional area,
remove strap from service.
WARNING
If damage to strap exceeds that allowed within
specification, do not operate crane until strap has been
replaced.
Operating crane with a damaged strap can cause
structural failure or collapse of boom, jib, mast, or other
